A little bit ago I bought my phone, and it started happening I believe when I installed Stock Rom + Xionia Beta 2 I read somewhere else that a hard reset is necessary to allow the system files to reload or something along those lines, or does anyone else have a solution or any similar problems? Remember, The phone reboots and when it starts up it says SD card removed then I take it out and reinsert then it's fine, it's the stock SD card.
